I've read a couple of reviews of Trisquel GNU/Linux, an Ubuntu-based distribution which aims to remove as much non-free (i.e. proprietary) software from the kernel and distribution as possible. There are a couple other distributions that do this, like Slackware-based Kongoni, KNOPPIX-based Musix, and Fedora-based BLAG. However, as stated by Jim Lynch in his review of Trisquel 4.0 LTS "Taranis", quite a few of these other pure-free software distributions, such as Musix, BLAG, and DYNE:BOLIC, share a few common features which all conspire to turn off potential new users: incomplete/amateurish websites, too much talk about "overthrows" of proprietary software or free software "revolutions" (to the detriment of promoting the features of the OS itself), and less-than-user-friendly DEs/WMs (e.g. WindowMaker).
